VENTILATING WINDOW SHADE.

Application illed. August 14, 1920, Serial No. 403,569. Renewed Hatch 6, 1923.

To all whom it may concern.

Be it known that I. Vieron M. ALLEN, a citizen of the United States, and a resident of Waverly, in the county of Tioga and State of New York, have invented certain new and useful Improvements in Ventilating lVindow Shades, of which the following is a specification.

This invention relates to Ventilating window shades of the general type shown in Letters Patent No. 1,329,352, granted to me February 3, 1920, the present improvement seeking to simplify the construction and operation Without any decrease in eiiiciency.

A particular object of the present invention is to provide a simple, inexpensive and effective means for holding the shade in a set position, and a further object is to simplify and improve the frame which carries the shade.

A still further object is to provide means whereby the hanging or removal of the shade will be expedited, and other incidentalobjects will appear in the course of the following description. y

One embodiment of the invention is illustrated in the accompanying drawings, wherein I Fig. 1 is an elevation window shade;

Fig. 2 is a vertical section ofthe shade;

Fig. 3 is an enlarged elevation of the weight-carrying rod with the adjacent parts ofl theframe in section;

Figs. 4 and 5 are enlarged detail Views showing di'erent adjustments of the locking mechanism;

Fig. 6 is a detail ing means;

Fig. 7 is a detail section taken longitudipanel sustaining rod;

Fig. 8 is a detail section on the line 8 8 of the Ventilating elevation of the supportj of Fig. 5;

Fig. 9 is a detail section on the line 9 9 of Fig. 3;

Fig. 10 is a plan 'view of the end links of the shade-carrying frame; and

Fig. 11 is a detail plan view of one Iof the shade panels.

In carrying out my present invention, I construct the shade in a plurality of panels 1, each consistin of a stri of textile fabric or other suita le materia of proper dimensions having a hem 2 along each longitudinal ed' e. and a rod 3, inserted through eachzhem.. he rods 3 are longer than the vor sockets 19,' 1n any one4 fabric strip so that the ends of the rods project beyond both ends of the fabric as shown in Fig. 11. The lrods have their ends engaged in sockets 4 in the frame bars 5 and should be stout enough to hold the fabric strip tau/tl but should be also pliableor resilient so that they will readily-spring into the sockets when registering therewith and may be easily withdrawn -by flexing. It will be readily understood that this ease of inserting and removing the rods greatly facilitates the work of repairing or replacing a torn or otherwise damaged panel, so that the old panel may be removed and a new one substituted therefor in a few minutes by an unskilled person without the use of any tools. The frame bars 5 may be of wood or light metal but should be sufii ciently rigid to maintain the spacing of the rods 3 which are fitted thereto at regular intervals. Obviously there are two frame bars 5 at each edge of the shade and they are 'connected at their upper and lower extremities by links 6 which are provided at their ends with suitable openings to receive rods 7 which extend between the corresponding bars 5 and forni pivots for the links.

Upon reference to Fig. 3 it will be noticed the pivot rod 7 is provided at one end with a head 8 to seat in a. socket in the side of the frame bar 5, while its opposite end is somewhatreduced and threaded, forming a tenon 9, to engage in a fastening nut or socket 10 having a head 11, similar to the head 8, seating in the adjacent frame bar v and provided with a notch or recess 12, to be engaged by a suitable turning tool. The frame bars are thus effectually held against spreading while being free to move pivota-lly with respect to the links.

The links are provided on their outer sides midway their ends with headed trunnions 13, which' are adapted to seat in notches 14 in the upper edges of bearing plates 15 which are secured to the window frame 16, at the inner side of the sash, indicated conventionally at 17. The trunnions obviously may rock in the notches 14, and their heads will prevent them from the bearing plates. One of the upper bearing plates is provided'with an enlargement 18 having a circular series of openings of which' a stop pin or screw 20, may be engaged to projectv into the path of the adjacent link and limit the movement of the same under the infin;

from pulling laterally y linee of a weight :2l which is hung on one tionlso that the entire window will be shaded shade may `horizontal position so as and no light may pass. lf the stop be in- "serted, however,in position to be engaged by the lower edge of the adjacent link 6, vas shown'in Fig. 5, the downward movement will be arrested and the shade will be held in a set position'determined by the location ofthe stop, the spaces between the different panels will be unobstructed and air from the open window may pass to ventilate the room. Should there be an abnormal increase of wind, the shade will not be blown about but the panels will assume a to present their edges to the wind and permit it to pass freely, the links 6 rocking "on their trunnions v13 to'accommodate the movement, as will i shown in be readily understood. lf it be desired to have the downward inclination of the panels toward the window, or outwardly, the

weight 21 is shifted to the outer rod 7, and

the stop20 arranged above the link 6, as Fig. 4. The action .under a high wind is then' the same as before except that the rocking is in the opposite direction.

" -The shade is supported at both top and bottom so that it cannot flap around and destroy or damage furnishingsnear the window but it can obviously be adjusted to admit any desired volume of air and light. When it is desired to clean the window, the be removed by merely lifting the trunnlons 13 from the seats 14:.

'It is v obvious that the panels-or louvers `mayifbe made'of wood or light metal and be used for porch shades or Venetian blinds.

lt is also obvious that there are no angles or hollow spaces present in any of the parts and that the device may be packed for shipping with absolutely no waste of space and may be shipped by mail if desired.

Having thus fully described my inven-` frames, headed trunnions on said frames between the sides of the saine at the ends thereof to seat in said notches and engage over the edges of the brackets whereby to pivot` ally support the frames in balanced position, spaced panels carried by said frames, gravitating means tending to hold the panels in a vertical position, and means for limiting the movement of the panels toward the vertical position. A

2. The combination offixed brackets havingnotches in their upper edges, an eXtension at the end of one of the brackets having a series of sockets extending above `and below the horizontal plane of the bracket,

foldable frames having trunnions engaging in the notches in the brackets, a shift-able gravity device hung on the frames to tend to effect folding thereof@ stop pin insertible in one of said sockets to bear against an adjacent member of the foldable frames and limit the folding movement of the frames, and spaced panels carried by said frames. 3. A Ventilating window shade comprising pairs of vertical bars, links extending between corresponding ends of the bars of each pair of bars, the bars having seats in their outer sides, pivot rods inserted transversely through the meeting ends of the links and the bars, said rods being each provided at one end with a head fitting in one of the seats in one of the bars, and a headed nut engaging over the opposite end of the lgod and fitting in the adjacent seat in the 4.1n a Ventilating window shade, the combination of framevbars, links extending between the ends of the frame bars, pivot rods connecting the ends of the links to the adjacent ends of frame bars, a weight bar having hooks encircling one of the lower pivot rods,vand spaced panels carried by the frame bars.
